Project description:A 50-year-old man presented with an episode of chest pain. Cardiac magnetic resonance revealed the presence of a large ventricular septal aneurysm partially closing a perimembranous ventricular septal defect, prolapsing into the right ventricular outflow tract, and mimicking a mass. We illustrate the diagnostic approach and management of such ventricular septal aneurysms. (Level of Difficulty: Advanced.).

Innocent left ventricular outflow tract membrane masquerading as vegetation.

Project description:Innocent left ventricular outflow tract (LVOT) membranes are a rare entity and found incidentally on echocardiography. The authors report a case of innocent LVOT membrane in a patient who was admitted with ischaemic stroke. Initial transthoracic echocardiography showed a possible valvular vegetation which was thought to be the cause of embolic stroke. Anticoagulation with coumadin and antibiotics were started. Subsequent Transesophageal echocardiography showed that it was more consistent with innocent LVOT membrane and not vegetation. Anticoagulation and antibiotics were discontinued, and on a follow-up over 5 years later, the membrane was stable in size and location without any complications.

Transcatheter Closure of Left Ventricular Outflow Tract-to-Left Atrium Fistula.

Project description:Surgical and rarely transcatheter aortic valve replacement can be complicated by intracardiac fistula. Transcatheter closure of those shunts has been previously reported with favorable results. We describe a case of percutaneous closure of left ventricular outflow tract-to-left atrium fistula after surgical aortic valve replacement using an Amplatzer Vascular Plug II. (Level of Difficulty: Advanced.).

An Unusual Case of Left Ventricular Outflow Tract Pseudoaneurysm.

Project description:Left ventricular outflow tract (LVOT) pseudoaneurysm is a rare condition with a wide range of causes and various clinical outcomes. The causes range from infections, trauma to the chest wall, and iatrogenic origins. We present a unique case of idiopathic LVOT pseudoaneurysm in a patient with no obvious clinical risk factors. (Level of Difficulty: Advanced.).

2 Cases of Elusive Left Ventricular Outflow Tract Gradient.

Project description:Patients with hypertrophic cardiomyopathy (HCM) typically have septal hypertrophy and left ventricular outflow tract gradient, usually present at rest with increase under certain hemodynamic conditions. We report 2 cases of HCM in which there was subtle septal hypertrophy; the gradient was detected only postprandially, highlighting the importance of considering postprandial imaging in patients with suspected HCM. (Level of Difficulty: Intermediate.).

Female Fabry Patient With Left Ventricular Outflow Tract Obstruction.

Project description:BackgroundCardiac involvement in Fabry disease is usually characterized by left ventricular hypertrophy (LVH) without obstruction at rest.Case summaryA 59-year-old female patient with progressive chest tightness misdiagnosed as having hypertrophic cardiomyopathy due to LVH with obstruction was finally diagnosed with Fabry disease. Echocardiography showed LVH with severe obstruction, "binary sign," papillary muscle hypertrophy, and depressed longitudinal strain in the basal inferolateral region. The patient felt chest tightness worsened 1 year after receiving enzyme replacement therapy. Percutaneous endocardial septal radiofrequency ablation was performed to relieve obstruction.DiscussionIt is rare for women with Fabry disease to present with severe symptoms, but it is possible. LVH with obstruction should not be a potential point of view to relax the vigilance of Fabry disease. Percutaneous endocardial septal radiofrequency ablation may help to relieve left ventricular outflow tract obstruction in Fabry disease.Take-home messagePaying attention to echocardiographic characteristics is helpful for the identification of Fabry disease.

An unusual cause of left ventricular outflow tract obstruction.

Project description:Left ventricular outflow tract obstruction (LVOTO) has been reported with bio-prosthetic and mechanical mitral valves (MV), though it is more common with the former. The obstruction can be dynamic or fixed. We hereby report a case of fixed LVOTO following bio-prosthetic MV replacement (MVR).

Unstable angina complicated with dynamic left ventricular outflow tract obstruction.

Project description:Left ventricular outflow tract obstruction (LVOTO) complicated with unstable angina (uAP) has not been described widely, but patients with these two conditions have several problems. Differentiation of the two conditions is also often difficult because the chest symptoms are similar. Moreover, nitrates are commonly used for ischemic heart disease, but have the effect of worsening LVOTO. We experienced three cases of dynamic LVOTO with a sigmoid-shaped septum, and without typical hypertrophic obstructive cardiomyopathy, that were complicated with uAP. In all cases, LVOTO was improved after initial percutaneous coronary intervention (PCI) for the left anterior descending artery lesion. Next, a dobutamine stress test was performed and LVOTO was provoked again in two cases, but not in a case with small acute myocardial infarction of the basal septum during PCI. All cases remained asymptomatic with beta-blocker therapy. Therefore, PCI and beta-blocker administration for LVOTO with uAP resulted in favorable clinical courses in all three cases. These outcomes suggest that revascularization including PCI should have priority in the therapeutic strategy for a case of acute coronary syndrome with LVOTO.
